Satellite image of glaciers and icefields
Location: Bylot Island, Nunavut, Canada; NTS 38C Bylot Island & 38B Pond Inlet;
False-color image from LANDSAT 1 satellite. Image E 1748-16544 shows the
extent of glaciers and icefields on Bylot Island and adjacent Baffin
Island (Pond Inlet to the east and Eclipse Sound to the west separate
the two islands; town of Pond Inlet is also indicated). Light-colored
areas along the coastline at the top of the image represent areas
dominated by vegetation-free cabonate debris transported onshore by a
major glacier that flowed down Lancaster Sound north of Bylot Island and
expanded as it emerged into Baffin Bay during the last glacial maximum
(Klassen, 1993; and
Klassen and Shilts, 1987).
Most tundra flora on the island are
acidophilic and will not tolerate the alkalinity of the soils on these
carbonate-rich sediments. Labels on individual glaciers are derived from
Area 46201 on the
Baffin Island Index Map
(Glacier Atlas of Canada, 1972).
Image Available without labels.
